Freeze dried food is lightweight and easy to store, making it the perfect food for expeditions. It’s also high in nutrients and calories, so it’s a great way to make sure you’re getting all the nutrients you need. In this article, we’ll explore the benefits of freeze dried food and how it can help you on your next expedition.
What is Freeze Dried Food?
Freeze dried food is a type of food that has been dehydrated and had the water removed from it. Freeze drying is a process that involves freezing the food, then vacuum drying it. This removes the water from the food, leaving only the solid ingredients. The food is first placed in a large freeze drier which is set to very low temperatures that freeze the food, turning it into a solid. The dryer has a vacuum on the inside that removes any moisture from the food. This can take anywhere from one to ten days, depending on the food item.
The Benefits of Freeze Dried Food
Freeze dried food is lightweight (about 90% lighter than the original food), easy to carry, compact and easy to store, making it ideal for camping, travel and expeditions. When dehydrating food, between 98%-99% of the water is removed, but almost all of the nutrients remain. This makes freeze dried food a great source of energy and nutrients, which is ideal for situations where you need high quality, nutrient rich food that needs to fit in a rucksack and not slow you down. Obviously, when planning an expedition, it’s important to get enough calories each day to fuel your body, so depending on the duration of the trip you may need large quantities of food, so weight and volume are absolutely essential.
The Best Freeze Dried Foods for Expeditions
When planning an expedition, it’s important to choose the right freeze dried foods. The best types for expeditions are specialist pre-prepared meals, and energy dense snacks. These meals are available in individual pouches that are extremely compact and robust – easy to include in a rucksack. They are also waterproof, meaning that they won’t get spoiled in bad weather or accidental submersion. They are quick and easy to prepare – the usual method is to simply tear off the top and add hot (or cold) water, then wait for 10 minutes. The meal can be eaten directly from the pouch if necessary. As they have been developed with survival conditions in mind, there are rich in vitamins and minerals, high in energy and other nutrients.
How to Store Freeze Dried Food
When storing freeze dried food, make sure to keep it in a cool and dry place. Make sure to keep it away from moisture, as this can cause the food to rot. When storing freeze dried foods in your backpack, make sure they’re in a sealed container to prevent them from getting wet (specialist products will already be packaged suitably, so this won’t be a concern for those). Freeze dried foods need to be rehydrated before eating them – when rehydrating, make sure to use clean water as dirty water can contain germs or other pathogens that could make you sick.
What to Look for When Buying Freeze Dried Food
When buying freeze dried foods, make sure to read the label and check for the words “freeze dried.” Many foods are dehydrated, but not all of them are freeze dried. Freeze dried foods are more expensive than dehydrated foods, but they’re well worth the price. Freeze dried foods are lightweight, compact, convenient, easy to store, and full of nutrients and calories. They’re also easy to rehydrate and can be eaten as is. When planning an expedition, it’s important to choose the right freeze dried foods, with specialist survival food and meals being the optimal all round solution.
